Outline of Final Research Achievements

We applied superconducting quantum interference device (SQUID)-based magnetoencephalography (MEG) to measure both normal brain function and epilepsy-related abnormal activity for future development of tunnel-magnetic-registance (TMR)-based high resolution MEG system. Subjects were people with epilepsy with focal cortical dysplasia, with various types of age-dependent epilepsy, or with interhemispheric foci; and normal subjects. Time-axis waveformes and sensor-based isofield maps were analyzed for both epileptic and normal auditory function. These basic data can be used to apply future development of high-resolution MEG system using TMR sensors.
